1890 – 1958
Eino Kaila (1890–1958) was a Finnish philosopher and psychologist who became the leading figure of logical empiricism in Scandinavia, maintaining close ties with the Vienna Circle. He developed a sophisticated philosophy of nature grounded in invariance relations and pursued a rigorously scientific worldview that nonetheless resisted reductive physicalism. His work bridged empiricist epistemology, gestalt psychology, and the philosophy of science.
